G-Power Pumps More Muscle Into Mercedes-AMG C63 S

With a little help from G-Power, this Mercedes-AMG C63 S has overcome its initial limitations, venturing perilously close to supercars in terms of performance.

The tuner has achieved this by adding their Performance Module to the stock ECU. The aftermarket part “modifies the data recorded by the vehicle sensors with the aid of a microprocessor, and then forwards the adapted information to the standard ECU of the C63 S”, explains G-Power.

As a result, the twin-turbo 4.0-liter V8 engine now churns out 600PS (592hp / 441kW) and 800Nm (590lb-ft) of torque. The extra 90PS (89hp / 66kW) and 100Nm (84lb-ft) can also be achieved with the tuner’s Performance Software V1, and is joined by an increased top speed of 300km/h (186mph). All things considered, this Mercedes-AMG C63 S takes as little as 3.8 seconds to sprint from naught to 100km/h (0-62mph).

Said to “guarantee optimal compatibility with the engine”, G-Power’s upgrades are also available with an optional stainless steel sports exhaust system. The latter enhances the symphony coming from underneath the hood.

A more extreme upgrade is also in store, raising the car’s power to an impressive 800PS (789hp / 589kW). The number is achieved with more software modifications and some fine-tuning of the turbocharger and exhaust system.

There are no weird body kits equipping this Mercedes-AMG C63 S, as the final product only features a new set of wheels. Called Hurricane RR, the forged rims measure 20-inches in diameter and have a black finish.
